IMPROVEMENT m HOMOMOTIV'E.

The Schedule referred to in these Letters Patent and making part of thesame.

The gear-wheel m is fixed to, or preferably forms a direct part of apawl, or pawl-driven wheel 0, having To all whom it may concern:

Be it known that I, WILLIAM SMITH HALL, of Quincy, in the county of- No'rfolk, and State of Massachusetts, have invented a Homomotive; and Ido hereby declare that the following, taken in connection with thedrawings, which accompany and form part of this specification, is adescription of myinvention sulficient toenable those skilled in the artto practise it.

United States Letters Patent, No. 65,665, dated sides, with whichflanges engage two clutch or frictionpawls, or gripes q.

Each of these pawls is hung at the end of a pawllever, r, fulcrumed androcking freely on the shaft n, the opposite arm of the lever beingattached to one end of a spring, z, whose other end is attached to theframe a, the stress of each spring returningits lever to normal positionwhen released.

I Each pawl, or gripe is composed of two pins j,

projecting from an arm, 8, said arm having an oblong slot near its outerend, through which passes the screwpin t, by which it is hung to thepawl-lever, and the pins j j embrace the adjacent flange of thedrivingwheel.

Each arm s is pressed in a direction opposite to that in which it movesin driving the wheel, by a slight spring, u, theslot enabling the arm toassume a position in direct line with the pawl-lever, or a positionangularthereto.

When the spring u throws the arm into inclined position, the twoclutch-pinsj hug the flange of the wheel,

covers a peculiar system of springpawl levers, ratchetand-pawlmechanism, and double set of treadle-levers, pawl-levers, 850., soarranged that the actuated wheel or shaft may be driven by either or byboth treadles, and by any extent of movement of either or both, and mysecond patent (86,833) relates particularly to, and covers thecombination of the invention shown in the ism, and the peculiararrangement of a momentumwheel, and other details of the mechanism.

These inventions were designed for driving any light mechanisms capableof being advantageously operated by foot-power, and the peculiarorganization shown in the last patent was designed by me with particularreference to the adaptation of the inventions to driving light vehiclesby hand or by foot-power, or by both combined.

My present invention relates to this adaptatiom'and consists primarilyin a carriage having this mechanism arm so inclined, the pins will carrythe wheel with movement, while, if the movement of the lever bereversed, friction of the pins against the flange will bring will slipupon the flange, or the flange will run between the pinsavithoutmovement being imparted by them to the wheel, and without the pinsimpeding the free rotative movement of the wheel.

The mechanism thus described, for driving the shaft, is identical, inits general arrangement and method of operation, with that shown in mypatent, 86,833, the upper arm of each pawl-lever in said patent beingconnected with a treadle, by means of which either pawl may be actuatedsingl or both together, the momentumwheel, on a shaft auxiliary to thepawl-driven shaft, actingas an accumulator of the power exerted indriving the treadles.

In the carriage, I joiht to the upper arm of each pawl-lever the rearend of a horizontal connecting-rod, '21, whose front end is jointed to arocker-arm, w, hung on a cross-rod, x, in front of the dasher of thecarriage. The arm swings freely on this rod.

To the endof each rocker-arm w is fixed a pedalbar, 3 which projectsthrough a hole in the dashcrboard, and has, at its top, a pedal, z,preferably jointed ment;
